PITTSBURGH -- JuJu Smith-Schuster's Year 2 leap will have to wait.
Smith-Schuster, 21, the NFL's youngest player to record 1,000 total yards in a season, is limited in Pittsburgh Steelers minicamp with what he calls a "frustrating" knee injury.
Smith-Schuster won't disclose the nature of the injury but plans to be a full participant for training camp, which opens July 26. The Steelers have sidelined Smith-Schuster for all 11-man work in Organized Team Activities and minicamp.
